I used Dent Wizard In Tampa, Florida. He removed 3 dings, one in the trunk, all for about $110. Great work. Can't see any evidence of dings. I think Dent Wizard is a chain.

My PDR guy does it by the panel. The trunk can have 55 dings and it costs the same as 1 ding on the quarter panel. 65 dollars per panel, he quits charging at around 200
